Genus ASPATHA Sharpe. 



AspathaO' Sharpe, Cat. Birds Brit. Mus., xviii, 1892, 331. (Type, Prionites 

 gularis Lafresnaye.) 



Small Momotidae (length about 260 mm.) with bill shorter than 

 head, moderately depressed (its width at nostrils about equal to 

 or very sUghtly greater than its depth at same point), culmen not 

 distinctly ridged (except basally), tarsus decidedly longer than dis- 

 tance from nostril to tip of maxilla, tail (of ten rectrices) much less 

 than onc-tlaird longer than wing, the middle rectrices always with 

 webs continuous (uninterrupted). 



Bill shorter than head, about as wide as deep at nostrils (or very 

 sHghtly wider), broad and very shghtly tapering to near tip in ver- 

 tical profde, distinctly decurved at tip; culmen (from extreme base) 

 about one-third as long as wing, sUghtly convex throughout, strongly 

 decurved at tip, rather distinctly ridged for basal half, very indis- 

 tinctly if at all ridged terminally; gonys about one and a haK times as 

 long as mandibular rami, broadly rounded, without trace of median 

 ridge; serrations of tomia distinct only on middle tliird (approxi- 

 mately). Nostril moderate, oval, obliquely vertical, in anterior end 

 of nasal fossa. No prefrontal (postnasal) bristles; rictal bristles 

 moderately developed, those of malar apex larger and stronger, and 

 feathers of chin with long, recurved, bristly tips. Head completely 

 feathered, the auricular feathers elongated and somewhat stiffened, 

 producing a conspicuous tuft; a small tuft of elongated feathers in 

 middle of lower foreneck. Wing rather short and rounded, the 

 longest primaries exceeding longest secondaries by about length of 

 hallux without claw; fifth, sixth, and seventh primaries longest, the 



o 'A, without; anadr], a blade. (Richmond.)
